There's a few things I remember. Most of it was based around footage of the german people going to concentration camps and freaking out. it was pretty short, I think less than an hour?

But the big thing was it was in German I think and it had a thing at the beginning that very firmly started not for Americans.

I believe the post stated that it was only made for Germans to watch so that they realized the scope of what they had done, and so it was notable for the "you did this" vibe.

I don't know why I can't find it but if anyone knows where it could be, much appreciated. Thanks!
